WAGON-BRAKE.

To all whom it may concern: 1 7

Be it known that we, J O HN L.- PATTON and ARTHUR LQPATTON, of Panola,in the county of \Voodford and State of Illinois, have invented certain new and usefulImprovements in \Vagon-Brakes; and we dohereby'declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying draWingS,'Which form part of this specification.

' Our invention relates to an improvement in wagon-brakes; and it consists in the construction and arrangement of parts which will be fully described hereinafter.

The object of our invention is to so construct a brake that it is practically entirely under the box and out of the way when not in use by having the levers which carry the rub-blocks to contract or draw under the body, whereby mud will not collect upon it in wet weather and in cold weather freeze thereon and interrupt its operation, and which adds very much to the appearance of the wagon.

Figure l is an inverted perspective of a wagon-body having our brake applied thereto. Fig. 2 is a detached perspective of the endwise-moving rod, with which the inner ends of the rub-block levers engage, and the tripping-spring. Fig. 3 is a detached perspective of a portion of the lever, showing the incline for tripping the spring.

A represents the under side of a wagonbody, to which is preferably secured the two transverse bars B and the central transverse bar 0, to which the operating mechanism hereinafter described is secured. Extending the two end transverse bars B and at its center to the central bar (Land which is bulged or bent upward between the bars, as shown. Secured to the opposite ends of one of the end bars B and the central bar C is a Hat metallic bar E,'which is bulged upward between the said bars, and has its'inner end to extend slightly beyond the bar O,'as shown. Pivoted at one end to the extended end of the bar E is a lever F, to the opposite end of which is secured a rod G, the opposite end of this rod being attached to an ordinary operating-lever H, which is pivoted to the side of the wagon-body andheld in its adjusted position by means of a rack-bar and a pawl.

Pivoted to the center of the bar F is a rod I, the opposite end of which is pivotally connected to an arch J, which has its ends secured to an arm or lever K, which arm or lever is I pivoted at its center upon an endwise-moving rod L. The forward end of this rod L is bent upward, as shown at M, for the purpose hereinafter described, and has its opposite end to pass through a guiding-loop N upon one of the transverse end bars 13. Extending upward from the bar L are the two projections or rollers OP, which engage the inner ends of the rub-block levers Q R. Pivotally connected at one end to the ends of the pivoted arm K are the connecting bars or links S, which'have their opposite ends pivotally connected to the rub-block levers Q R. Extending downward from the inner end of the bar L is a projection 'l, which engages with an upwardly-extending projection upon the spring U, which has one end rigidly secured to the central transverse bar 0 and its opposite end turned downward, so as to engage by the inclined recess V, formed in the lever F. Secured to the rub-block levers Q R are suitable bars IV, which form guiding-openings, into which the projections X project and which form the fulora upon which the rub-block levers Q R turn when theyare being applied to the peripheries of the wheels.

\Vhen a pull is exerted upon the operatinglever H and the lever F is drawn toward the central bar C, it carries with it the bar I, which gtu rns the armj-K- into the position shown in Fig. 1, thereby throwing or moving outward the rub-block levers Q R, as'shown in the said figure. If the lever H is then moved in the opposite direction, thus throwing the lever F away from the central barC, a pull is exerted upon the bar I, which} is connected through the medium of the arch to the bar K, which will turn the bar K upon its pivot and throw the ends thereof inward, thus drawing the rub-block levers in under the wagon-body, as here shown. If, however, the lever H is forced on forward, the incline V engages the downwardly-turned end of the spring U, forcing it away from the bar L and thus disengaging the projections upon the spring and bar. As the lever F continues to move toward the central bar 0, it engages the upturned end M of the bar L and forces it forward, which carries, through the medium of the rollers 0 P, the inner ends of the rub-block levers with it, thus turning them upon the fulcrums X and throwing the rub-blocks against the wheels, as will be readily understood.

e preferably make the inner ends of the rub-block levers wed geshaped, as shown, and secure to the outer edge of the lever Q an inclined bar Y, which is more or less elastic and forces the inner ends of the rub-block levers together when they are moved outward into the position shown in Fig. 1.

By means of the construction here shown a brake is provided which is practically entirely under the body of the wagon and out of sight when not in use, and thereby adds very materially to the appearance of the wagon. It also prevents the accumulation of mud upon the rub-blocks in wet weather and also in freezing weather prevents the mud from lodgingand freezing upon the rub-blocks, and thus avoids one of the great disadvantages with rub-blocks which cannot be retracted under the body.

Having thus described our invention, we claim- 1. The combination of sliding and turning rub-block levers, a lever K, pivoted between its ends to the body connections between the ends of said lever and the rub-block lever, an operating hand-lever, and connections between the operating-lever and the lever K, substantially as shown.

2. The combination of a lever K, pivoted between its ends, the rul: -bl.0cklevers adapted to turn and slide, connections between the ends of the leverK and the rub-block levers, a lever F, a connection between the lever F and the lever K, an endwise-moving lever which engages the inner-ends of the rub-block levers, and an incline upon the inner end of one of the levers which engages the endwisemoving lever, for the purpose described.

In a wagon-brake, the combination, with sliding and turning rub-blocklevers, of an endwise moving bar which engages the inner ends of the rub-block levers, an arm pivoted at its center to the said bar, links connected with the rub-block levers and the ends of the arm, a pivoted lever, and a connection between the arm and the pivoted lever, substantially as set forth.

4. In a wagon-brake, the combination, with endwise moving and turningrub-block levers, of an endwise-moving bar which engages the inner ends of the levers, a bar pivoted at its center upon the endwise-moving bar, links connecting the rub-block levers and the ends of the arm, a pivoted lover, a connection between the pivoted lever and the pivoted arm, and a spring-catch which engages theendwise-moving bar and is operated by the pivoted lever, as described.

In testimony whereof weatiix our signatures in presence of two witnesses.
